I bought these to replace a total of 20 old and new working recessed lights. However, the built-in lights did not always fit perfectly with the ceiling and were a little irritating to the eyes. Candles are excellent, the whole family liked them. However, they are not ideal. The brackets that attach the lights to the ceiling are sharp and bend easily. Although none of them broke, it was close. Second, electrical boxes are pretty flimsy and you need to be careful when removing and opening the plugs. I also found that they didn't stay closed, so I wrapped the lid with duct tape to make sure they were closed. Also, they've been installed for about a month, they look great, they have a decent dimming range. The price doesn't reflect how attractive they are, I would definitely buy them again. I give 4 stars for the installation, the rest 5 stars.
